IEEE Industry Connections (IEEE‐IC) Landmarks and Measurement Standards Comparison in 3D Body‐model Processing Abstract This white paper reviews the current standards landscape for three‐dimensional body scanning, body landmarking, and measuring. International standards are compared and recommendations are made for a minimal set of landmarks and measurements (L&M) needed for several industrial use cases of 3D Body Processing such as fit and size estimation, retail, clothing manufacturing, CAD tool developers, and body model storage and service.
1. Introduction Human body structure is made up of 206 bones and 230 moveable and semi‐movable joints in adults [1], and its outer body surface can range from an average of 2205 cm2 at birth (50 cm, 3.5 kg) to 25,000 cm2 for a 300 kg, 190.5 cm obese adult [19]. Three‐dimensional (3D) scanners enable the fast, safe, and cost‐effective acquisition of body surface geometry in 3D. Since their appearance, 3D models of the human body (or body parts) have been in use for various applications and are becoming ubiquitous in industries such as apparel manufacturing and retail. The increase in availability of body scanning equipment that are able to digitize body surface in combination with the expected proliferation of applications that use body models, justify efforts to standardize some of the interactions concerning 3D body models and associated data.
The 3D Body Processing (3DBP) initiative aims to improve interoperability between producers and consumers of 3D body models and associated services. In turn, standardization will ease the development of innovative solutions using body models and accelerate scaling of 3D body‐model‐based applications.
One of the common usages for 3D body models is the extraction of body measurements from the model since it is an efficient alternative to traditional anthropometry. These measurements are used in a range of applications such as ergonomic design, garment construction, mass customization, health or physical fitness. These measurements include distances, heights, widths, lengths, or girths. Measurements thus constitute an important metadata that should be kept along the 3D data processing pipeline, described in first white paper published by the 3DBP Industry Connections group [24].
In traditional anthropometry, human measurers locate the anatomical body references (designated as landmarks) by palpation of bony prominences. These landmarks are used as reference points when taking manual measurements (e.g., by measuring the distance between landmarks). Measurements are made using traditional tools such as calipers and measuring tape (Kouchi, et al. [17]). The digital extraction of measurements from a 3D body model relies on the same steps (i.e., landmarking and then measuring) but the definition of the landmarks is based on searches on the body surface geometry because no palpation is possible of the digital data. Some scanning solutions offer both the physical scan capture as well as a post‐processing stage to calculate body measurements. In other cases, measuring software is offered as standalone software that accepts 3D body models from different scanners.

Measurement definitions, postures, anatomical body references, instruments, procedures, and attire are standardized for different purposes (i.e., ergonomic design of products and environments, health and physical activity) by different independent organizations such as ISO1, ISAK2, IEC3, CEN4 or ASTM5. In garment construction, there are also definitions provided by the different patternmaking methods (Aldrich [1], Armstrong [3], Beazley [5]) However, there are discrepancies among measurement definitions leading to, for instance, different definitions for the same designations (e.g., waist girth). Even though body scanners are presented as alternative measuring instruments in the latest versions of standard (ISO 8559‐1:2017 [9]; ISO 7250‐1:2017 [8]), for these applications, definitions are still based on manually palpated landmarks and do not consider the particularities and advantages of the digital methods. This means that each measuring software developer creates a different interpretation and implementation of the same measurements and landmarks. To address this issue, new standards have been recently released providing body measurements, landmarks, body part and joint definitions from a natively digital perspective for digital fashion applications (ISO 18825‐1:2016 [10], ISO 18825‐2:2016 [11]). Despite the fact that these standards constitute an important step forward, these definitions are conceived to work with digital human models rather than with actual body scans of people. Additionally, none of the previously mentioned standards considers a procedure for defining new measurements, which is common practice among body scanner and measuring software suppliers.
Regarding quality, in the case of manual measurements, the skill of measurer strongly affects the reliability of manual measurements (Kouchi, et al. [17]); moreover, compatibility among manual measurements is often compromised due to systematic errors between differently skilled measurers. Analogously, in the case of digitally elicited measurements, the quality of the 3D scans has a strong influence on the reliability of measurements; moreover, the compatibility among digital measurements is often compromised due to differences in the interpretation and implementations of different measuring software.
The main benefit of 3D scanners is that they provide the whole surface of the body, i.e., 3D body model, which cannot be provided by traditional anthropometry. The accuracy of the raw scan point cloud (or surface) acquired by a body scan of a rigid object is also addressed by ISO 20685‐2:2015 [12] and by proprietary procedures developed by manufacturers. However, it is not resolved for measuring living humans, which are soft and articulated. Moreover, the surface manipulations along the processing pipeline from the raw scan to the 3D body model is neither tracked nor quantified.
Within 3DBP initiative, the quality sub‐group intends to provide methods, tools, benchmarks, resources, and testing procedures to define and quantify the quality of 3D models, as well as the quality of the critical metadata for use cases, such as body landmarks and measurements. Quality quantification is intended to be part of the quality‐related metadata, which will provide complementary information about what the user receives and to what extent it is reliable, accurate, and trustworthy. Among the different steps within the 3D body processing pipeline (Figure 1), the sub‐group is initially focused on (A) 3D scanning, (B) mesh surface reconstruction,

(C) digital landmarking, and (D) digital measuring since they are the more relevant for the considered use cases.
Figure 1 : 3D Body Data Processing Pipeline (McDonald [20])
Within these four processes, the quality attributes considered so far are related to the following:
Descriptive information about the process, e.g., scanner supplier, scanner specifications, software version, scanning pose, or scanning attire.
Qualitative descriptors and quantitative metrics for the processed 3D surfaces related to noise, artifacts, redundancies, holes, smoothing, and surface reconstruction.
Reliability of body measuring software. Compatibility of digital body measuring and landmarking to methods dependent upon
different digital software and/or traditional methods.
This white paper provides some examples of the role of measurements in 3DBP use cases as well as discusses the current landscape of standards related to body measurements and landmarks, and identifies the gaps not covered by them. Moreover, it provides a shortlist of measurements and landmarks that will be used within the initial use cases considered by 3DBP initiative; i.e., fit and size estimation, retail, clothing manufacturing, CAD tool developers, and body model storage and service.
2. The role of landmarks and measurements in 3DBP applications
As noted in the first paper published by the 3DBP Industry Connections group [24], there are different building blocks that can make up a 3DBP solution, such as the following:
a. Scanning or acquisition of the 3D surface data b. 3D Model generation c. Landmarks and measurements (L&M) identification d. Digitization of objects (e.g., clothing, furniture) e. Aggregation of data from various sources f. Processing and integration of the data g. Presentation/display/output the results

An application may contain all or some of the previous building blocks. (Each of the blocks were described in detail in the first paper by the 3DBP group.) This paper focuses on landmarks and measurements (L&M) identification. Within this block, L&M are estimated by software that receives a body scan or a body model as an input. This software is not necessarily tightly coupled to the model generation step and can run on body models regardless of the scanner used to create them. Recognition and isolation of body parts may take place in this step as well. Some restrictions may apply. For example, the code may be expecting the subject to be scanned in a certain pose.
The following subsections give examples for how a 3DBP solution uses L&M. Implicit in the given examples is the understanding that certain landmarks and measurements must be provided with a model to make the use case possible.
CAD clothing design
The general procedure for constructing 3D garments with 3D‐CAD software can be broken down into the following steps:
1. Create patterns in 2D space 2. Position 2D‐patterns around the 3D‐body (avatar) 3. Virtually stitch of the 3D‐pattern 4. Simulate garment
In step 1, the accuracy of landmarks is of vital importance since 2D‐patterns are being drafted based on the measurements/sizes of the target body to achieve a good fit. These measurements (body lengths and depths) are based on landmarks, whose maximum allowable error between extracted value and traditionally measured value should be within ±5 mm (ISO 20685:2010 [12]). Body circumferences should be within ± 4 mm to 9 mm.
In step 2, the landmarks on a 3D‐avatar are used as reference locations for selecting arrangement points around a 3D‐body. The accuracy of landmark placement is less important if the CAD software can drape clothing correctly over the avatar even when the initial positioning of the clothing is not that accurate. Note that this applies only to certain CAD software; some applications do require accurate landmark placement to provide good draping results.
CAD footwear design and fitting
Another example for the use of L&M is footwear fitting. The main concern is the positioning of the foot while being scanned to achieve appropriate information. The foot can be in a fully weighted state (standing with body weight on one foot, or full‐weight bearing, FWB) or an unweighted state (sitting or with foot in the air; or non‐weight bearing, NWB). ISO/TS 19408 [15] states that measurements should be taken in an evenly weighted position between the two feet (half weight bearing, HWB). However, that may not be the best position for all use cases in footwear, especially if the underside of the foot should not be compressed. The foot measurements maximum allowable error between extracted value and traditionally measured value should be within ±2 mm (ISO 20685:2010 [12]). This is in the same order of magnitude as the differences between the different weight‐bearing conditions for different foot measurements, which can range from 3−7 mm depending on the measurement (Houston, et al. [6], Oladipo [21],Telfer and Woodburn [22], Tsung, et al. [23], Xiong, et al. [25]). Additional critical factors affecting L&M include the following:
9
Copyright © 2018 IEEE. All rights reserved.
Whether the foot is shod or unshod
Whether the foot is fleshy or bony, i.e., soft tissue
Whether the foot is wrapped, e.g., wearing a sock or in a cast
Whether the arch of the foot is raised or flattened, i.e., the windlass mechanism
3D CAD software for footwear design is different from CAD software for clothing design as the whole process is based on the shoe last and not directly based on the human body. Shoe lasts are not the 3D representation of the ideal foot that fits the shoe, but rather a constructive component of shoe manufacturing. Shoe lasts are used to define the final shape of the shoes, are impacted by the intended usage of the shoes, and are directly related to shoe fit. The use of lasts for shoe development dictates two approaches for foot scanning. The foot is either scanned with the intent of creating a last for product development or creating a model of the foot for product fitting. Scanning to create a model for fitting is further complicated by the dynamic change in foot shape with flexing and movement.
The shape of the shoe is not based on static criteria. Foot dynamics, inner structure, and soft tissue wrapping/compression play an important role in shoe design and must be accounted for in the foot scan.
3. Landscape of existing standards Independent organizations such as ISO, ASTM, and ISAK have already developed standards that are related to these topics, which cover partially the objectives of the 3DBP use cases. In particular:
ISO 8559‐1:2017 [9] and ASTM D5219‐15 [4] provide body measurement designations and definitions for garment construction
ISO 7250‐1:2017 [4] provides body measurement designations definitions for ergonomic design
ISAK [7] provides body measurement designations and definitions for shape tracking in health, sports and fitness
ISO/TS 19408 [15] provides foot measurements designations and definitions ISO 18825‐1 [10] and ISO 18825 2 [11] provide measurement and landmark definitions for
virtual models used in fashion applications ISO 20685 [12] and ISO/DIS 20685‐1 [13] provide 3D body scanning attire, compatibility
thresholds between traditional and digital body measurements ISO 20685‐2 [14] provides testing and reporting procedures for spatial quality of
unanimated objects (sphere), as well as procedures for landmark repeatability of life‐size human dummies and determination of hidden areas.
This white paper focuses on the differences and gaps of the landmarks and measurements mentioned in the standards shown in Figure 2 and Table 1. Any gaps in testing methods, thresholds, reference values, and test bench datasets may be addressed in future white papers.

Appendix A summarizes each of the standards listed in Table 1. Appendix B provides the full list of designations of L&M used in each of the standards. The list includes L&M of full body and body parts, namely head, feet, and hands.
Within 3DBP initiative, the quality sub‐group makes use of the existing definitions, procedures, and thresholds, and aims at filling the gaps required for regulating the 3DBP use cases that are not currently covered by them. Thus, the main aims are as follows:
Defining a procedure for reporting user‐defined measurements beyond standard definitions enabling their interoperability.
Defining procedures for qualifying and/or quantifying 3D quality of digitized bodies of living human bodies.
Defining procedures for quantifying reliability of body measurements and landmarks extracted from digitized bodies.
Defining procedures for quantifying compatibility across body measuring methods including both the digital and traditional methods.
Generating resources and reference quality data (benchmarks) related to the reliability and compatibility of 3D surfaces, measurements, and landmarks of living humans.
Establishing acceptability thresholds of reliability and compatibility for the different applications and industry use cases.
4. Detailed comparison of preferred landmarks and measurements from use cases
L&M are basic building blocks for designs that are based on the human body. It is therefore critical for interoperability that all practitioners in the field agree on a small standardized set of landmarks and measurements for use in conjunction with 3D body models. This includes definitions of L&M (the location on the human body) as well as the use of a common terminology (one set of names) for each landmark and measurement.
While there is a general agreement about landmarks and measurements between the standards, the actual names or locations given these items may differ. Additionally, some items exist in one standard and not in another.
The intention is to leverage the work done leading up to the current standards (mainly ISO 7250‐1 [8] and ISO 8559‐1 [9]) for the definition of L&M to be supported by preferred definitions.
The members of the 3DBP group are companies involved in 3D body processing (size recommendations, virtual fit, apparel CAD tools, body simulation, etc.). Together, the group reviewed many use cases and arrived at a list of twenty‐six landmarks for full body scanning as a minimum set needed to allow the reviewed use cases. Those landmarks are used to generate corresponding body measurements or for other goals (e.g., garment simulation).
The recommended landmarks and measurements are applicable to the use cases of retail, product development, and CAD developers. Further L&M may be added as additional use cases are explored.
Based on current practices of landmark identification in industry, as well as a comparison of ISO 7250‐1 [8] and ISO 8559‐1 [9], we concluded that ISO 8559‐1 is a more appropriate information source than ISO 7250‐1 [8], especially when it comes to 3D body processing. The
12

recommendation of this white paper is to follow ISO 8559‐1 [9] definitions unless otherwise specified. We decided to use ISO 8559‐1 [9] for the majority of L&M because of the following:
The designations used in ISO 7250‐1 [8] are based on anthropometric terminologies. The designations used in ISO 8559‐1 [9] are easier to understand or make more
sense for people without any knowledge in medical anatomy nomenclature. Additionally, ISO 8559‐1 [9] contains more detailed information with updated figures.
Some landmarks needed to support the use cases are defined in only one of the standards. In most instances, more landmarks are defined in ISO 8559‐1 [9].
Six landmarks defined in ISO 8559‐1 are not included in ISO 7250‐1. Only one landmark (vertex) in ISO 7250‐1 is not defined in ISO 8559‐1. This
landmark is used for height measurement.
Landmarks are defined differently in the ISO standards. Twelve landmarks are defined identically but have different names; other landmarks share the same names but have varied levels of differences in their definitions.
Required landmarks from use cases for full body
The standards compared have the L&M determined by traditional methods as explained in the introduction. The following tables provide details of twenty‐seven landmarks that are being recommended by the 3DBP group contributors from CLO, Gerber, Browzwear, TC², Zelus, and Intel for full body scanning. Table 2 describes the comparison between the standards and recommendation. Table 3 contains measurements that utilize the landmarks in the same format as Table 2. This is repeated for Table 4, Table 5, and Table 6 for body regions of head, foot and hand.
If there is no further comment within the table cells, the definitions of a landmark in ISO 7250‐1 and ISO 8559‐1 are identical, even though the actual terminology/name may be different. A table cell marked with an asterisk (*) indicates a difference from the definition of ISO 8559‐1.
Any landmark or measurement that is noted as “(L & R)” must be determined bilaterally. Those that can be measured or marked in one side only are noted as “(L or R)”; in such cases, it is recommended to use the largest or highest side and record which side is utilized.
PLEASE NOTE: There are known discrepancies between standard definitions. Where direct comparisons between these standards could not be found, definitions with a close correlation were chosen.

5. Summary and recommendations This white paper is the second in a series of papers that describes the 3D Body‐model Processing (3DBP) Industry Connections group recommendations to the IEEE P3141, Draft Standard for 3D
21
Copyright © 2018 IEEE. All rights reserved.
Body Processing Committee. The first paper gave the rationale for a 3DBP standard as well as an overview of the possible benefits to the industry.
This white paper provided a review of existing standards that are relevant to the 3DBP initiative. Landmark and measurement definitions in many standards were compared and a short list of twenty‐seven landmarks and thirty‐nine measurements were recommended for inclusion in 3D body model files. The L &M definitions and terminology are mostly based on ISO 8559‐1 and use other sources when needed landmarks and measurements are not defined in ISO 8559‐1. These L&M that are based off of traditional methods were then compared to the digital definitions in ISO 18825‐2 [11].
Current 3D body‐model files do not contain information that can help assess the accuracy of the model they represent. The 3DBP group is investigating possible ways to deal with this issue. A discussion of model accuracy and what (if anything) can be said about model accuracy is the topic of another white paper, intended to be published later in 2018. Along with accuracy, the other topics to be presented in future white papers are as following:
1. Dealing with user‐defined measurements from a purely digital perspective (from 3D body models) beyond standard definitions, which is the case of most body, foot, and head/face scanner manufacturers. In addition, a recommended procedure on how to report the measurements for interoperability will be presented.
2. Dealing with 3D quality of digitized body shapes of living human subjects, addressing both accuracy/validity and precision/reliability. The basis for calculation for precision, reliability, and accuracy will be proposed so that the error ranges are defined in universal recognized methods.
3. Dealing with tracking reliability of measurements and landmarks—this is the consistency of repeated measurements from the same person scanned at different instants. The basis for calculation for precision and reliability will be proposed so that the error ranges are defined in universal recognized methods
4. Dealing with compatibility and interoperability between measurements taken with different methods/sources, both between manual to digital and among digital thereby improving traceability. In addition, a recommended procedure on how to gather and report reference data will be presented.

Summary of content of 3DBP‐related standards
ISO 7250‐1 (2017)
Basic human body measurements for technological design—Part 1: Body measurement definitions and landmarks
The 2017 version defines 21 landmarks and 62 body measurements. The standard provides the following:
— Reference to measurement conditions and the type of equipment used — Landmark definitions — Body measurement definitions: While subject stands, a Standing subject While subject sits, a Seated subject Measurements on specific body segments Functional measurements
ISO 8559‐1 (2017)
Garment construction and anthropometric surveys—Body dimensions
The standard contains definitions for 93 body dimensions in the garment industry. Some of these coincide with body measurements defined in ISO 7250‐1, while others are specific to measurements of garments.
The standard provides the following:
— Landmark and level definitions — Line and plane definitions — Some reference to measuring conditions and apparatus — Body measurement definitions: Vertical measurements Breadth, width and depth measurements Girth measurements Distance measurements Hand and foot measurements Calculated measurements
ISO 20685:2010
3‐D scanning methodologies for internationally compatible anthropometric databases
— Defines how to measure people and verify the accuracy of the data, so that results are valid for human body measurement databases.
— Refers to ISO 7250‐1 for the definition of measurements
25
Copyright © 2018 IEEE. All rights reserved.
— Defines four positions of the human subject (e.g., A‐pose; sitting)
— Defines the maximum mean difference allowed between the scanner results and the anthropometrist results, to be considered sufficiently accurate.
— Defines the sample size of scanned people to meet a 95% confidence interval for the mean difference between measured and scanned measurements.
— Lists recommended clothing to use while scanning.
— Provides a protocol for evaluating the comparability between manual and scan‐derived measurements.
ISO 20685‐2:2015
Ergonomics—3‐D scanning methodologies for internationally compatible anthropometric databases—Part 2: Evaluation protocol of surface shape and repeatability of relative landmark positions
This part of ISO 20685 addresses protocols for testing of 3‐D surface‐scanning systems in the acquisition of human body shape data and measurements.
The standard applies to the landmark positions determined by an anthropometrist. It does not apply to landmark positions automatically calculated by software from the point cloud.
The tests are aimed at verifying:
The intrinsic accuracy of the scanner using a known‐size ball placed at various locations in the scan volume
The repeatability of landmark placement when the subject stands at slightly different positions within the scan volume
International Society for the Advancement of Kinanthropometry (ISAK)
International Standards for Anthropometric Assessment (a guide)
ISAK created a comprehensive anthropometric guide. They offer anthropometrist training classes and certifications at a number of levels.
